Abstract

PURPOSE: To efficiently remove and recover arsenic, by effectively treating an aqueous soluion containing at least arsenic and iron using iron-oxidizing bacteria.
CONSTITUTION: In the first step, an aqueous solution containing at least arsenic and ferrous ion above an amount equivalent to that of said arsenic is neutralized to a pH of 2.0W2.8 and then separated into a liquid and solid matter. The liquid is sent to the second step. In the second step, arsenic in the liquid sent from the first step is reacted with ferric ion returned from the third step undermentioned, to precipitate it as ferric arsenide. In the third step, the liquid after being dearsenided is introduced into an oxidizing tank, where ferrous ion in the liquid is oxidized into ferric ion by iron-oxidizing bacteria. The resulting liquid is returned to said second step. The iron-oxidizing bacteria in the third step are circulated together with the precipitate formed in the third step to the oxidizing tank for its reuse. A part of the liquid after being oxidized is returned to the second step, while the remainder is used for recovering the precipitate.
